GHK-Cu: peptide of the week

What is GHK-Cu?

GHK-Cu is a naturally occurring copper-binding tripeptide (glycine-histidine-lysine) first isolated from human plasma in 1973.

How it works

It delivers copper to cells and has been shown in lab studies to influence the activity of many genes tied to collagen production and tissue remodeling.

What researchers are studying

• ●Skin repair and collagen in cosmetic research
• ●Wound healing in animal models
• ●Hair-follicle biology

Where the evidence stands: Widely used in topical cosmetic products. Not approved by the FDA as a drug.
